Prussian blue analogues of Ni-Co-MoS nanozymes with high peroxidase like activity for sensitive detection of glyphosate and copper.

The rational development of efficient nanozymes for the colorimetric detection of targets is still challenging. Herein, Prussian blue analogues of Ni-Co-MoS nano boxes were fabricated for colorimetric detection of glyphosate and copper ions owing to its peroxidase like activity. At the sensing system, the Ni-Co-MoS nano boxes display high peroxidase activity, which could catalytically oxidize the colourless TMB to blue colour oxTMB.

Wearable sensor platforms for real-time monitoring and early warning of metabolic disorders in humans.

Nowadays, the prevalence of metabolic syndromes (MSs) has attracted increasing concerns as it is closely related to overweight and obesity, physical inactivity and overconsumption of energy, making the diagnosis and real-time monitoring of the physiological range essential and necessary for avoiding illness due to defects in the human body such as higher risk of cardiovascular disease, diabetes, stroke and diseases related to artery walls. However, the current sensing techniques are inconvenient and do not continuously monitor the health status of humans. Alternatively, the use of recent wearable device technology is a preferable method for the prevention of these diseases.

Fabrication of self-assembled nanostructures for intracellular drug delivery from diphenylalanine analogues with rigid or flexible chemical linkers.

Self-assembly of molecular building blocks is a simple and useful approach to generate supramolecular structures with varied morphologies and functions. By studying the chemical properties of the building blocks and tuning the parameters of their self-assembly process, the resultant supramolecular assemblies can be optimized for the required downstream applications. To this end, in the present study we have designed and synthesized three different molecular building blocks composed of two diphenylalanine (FF) units connected to each other through three different linkers: ethylenediamine, succinic acid, or terephthalaldehyde.

The design and development of short peptide-based novel smart materials to prevent fouling by the formation of non-toxic and biocompatible coatings.

Biofouling refers to the undesirable process that leads to the accumulation of microorganisms such as bacteria or fungi on substrates. This is one of the major concerns associated with several components of our regular life such as food, health, water and energy. In the healthcare sector, biofouling on medical devices is known to cause infections, which are often resistant to conventional antibiotics and lead to increase in the number of hospital and surgery-related deaths.

Pharmacovigilance of the cutaneous drug reactions in outpatients of dermatology department at a tertiary care hospital.

Objective: To study the various clinical patterns, causality, severity, and preventability of cutaneous drug reactions among the out patients of the Dermatology Department in a tertiary care hospital.

Methods: One hundred eighty one patients with suspected drug allergy were screened and 59 patients with Cutaneous Drug Reactions (CDRs) were recruited for this observational study which was conducted among the outpatients in the Department of Dermatology from June to December 2011. The history of drug intake, the morphology of the cutaneous reactions and their causality, severity and preventability were analyzed.
